You’re in luck because 7 just happens to be a reboot (of sorts) with an entirely new protagonist, cast of secondary characters as well as gameplay. Even its setting and crime organizations steer away (mostly) from the previous conflicts of the Kamurocho red light district.
Yakuza also has the an advantage (IMO) that its “how anime bullshit is this anime?” is fairly low. The characters are actual adults, dealing with (mostly) relatable to real life issues, and even the stories that are far out there (such as fighting a giant roomba) are not very egregious.
I certainly prefer the series as a whole than Persona, which I admit is an unpopular take. If you’re ever curious about doing a deep dive, 0 is also very welcoming and its the (now canon) beginning of the previous series.
